- Zo (ZZZ whom it may concern:

Be it known that LCHARLEs L. BROWN, a citizen of the United States, residing at Philadelphia, county of Philadelphia, and State of Pennsylvania, have invented a certain new and useful Improvement in Aeriahflable Supports, of which the following is a specification.

My invention relates to a new and useful improvement in aerial-cable supports, and has for its object to provide an aerial-cable support which may be easily and quickly socured or clamped upon the supportmgstrand and which will keep its place under all conditions and may be quickly removed from the strand at any time; and a further object of my improvement is to provide a support which can be manufactured at a comparatively small price and yet be extremely durable.

With these ends in view this invention consists in the details of construction and combination of elements hereinafter set forth and then specifically designated by the claim.

In order that those skilled in the art to which this invention appertains may understand how to make and use the same, the construction and operation will now be described in detail, referring to the accompanying drawings, forming apart of this specification, in which-- Figure 1 is a front elevation of my improved support attached to a supportingstrand; Fig. 2, a side elevation of my support attached to the strand; Fig. 3, a front elevation of a modified form of my im roved support; Fig. 4, a side elevation of 3 Fig. 5, a plan view of Figs; 3 and ,4.

In electrical work aerial cables are now used to a considerable extent, and these cables are supported from a sus' ension strand or wire which has previously een pulled up tightly from one pole to the other or when ever it is desired to suspend a cable, and from this suspension strand or wire depend hang ers or cable-supports s aced, usually, from one to two feet apart, t IIOU h which the cable passes. In attaching these cable-supportsor hangers various methods are in use, some requiring the forming of a marline loop over the cable, others the use of pliers or clamps to properly adjust them in order to have the su port or hanger remain in the position it is st placed.

My invention is for the urposo of providing a support or hanger w rich will automatically clutch the strand of wire and does not need any clamping-tool or pliers to secure the support to the strand.

My improved support is made of one iece of wire, said wire being bent in the mid is to form a ring or loo A, through which the cable is designed to e drawn. The two ends of the wire then pass upward side by side, said Wires while still being in alinement with one another ale bent'so'as to form. a hook B, adapted to hook over the strand from one side, and then the ends of the wire at the point E are bent outward in two opposite directions, so as to form the arms 0. Said arms pass downward around the strand upon the opposite side from the hook B, and the ends of said arms extend underneath the strand, as shown in Fig. 2, each arm thus forming an elongated spirally-formed hook engaging the strand from the opposite side of and hook B are so formed with relation to one another that in order for the strand-wire to pass between the arms C and hook B in their normal position said strand-wire would have to be bent out of a straight line, or, in other words, the tendency of the arms C is always to press inward in the opposite direc tion to which the hook B woul be pressing, and this would tend to force the strand-Wire out of a straight line; but, as a matter of fact, the strand-wire is drawn so taut that it remains ractically in a straight line, and the wire of t 1e support gives, but still exerts a pressure, and thus forms an exceedingl stron and efhcient clutch, and the clutc tightly upon the strand and prevent any sliding movement of the su port along the strand. It will be seen ti at by this construction a great amount of tension can be exerted against the strand, lthough the support may be made of comparatively small wire, for the tension caused by atwisting movement in the neck of the support.

In Fi s. 3, 4, and 5 e modification is shown in whic i the arms C do not form the hooks themselves, but are provided upon their outer ends with vertical hooks D, engaging the strand-wire from the opposite sides toihut engaged by the hook B. The arms (1 in this case extend above and parallel with: the strand, the hooks D being formed integral with the wire at the outer end of cach'of the arms. The action in this case is exactly the same as that shown in Figs. 1'. and 2, and the that engaged by the hook B, and the arms C thus ormed will cause the support to be held prineiple of the invention is therefore the same. It will be noticed in Fig. 4 that theh'ook-shaped portions B and D, which eontaet the'strand, are not formed so as tooonform with the rotundity of the strand, but are so shaped that when the strand is engaged by these hook-shaped portions said portions will'only contact the strandon its upper and lower surfaces, leaving aspace bealso be applied to that form shown in Figs. 1 V

tween the strand and the bend of the hook, so that the-strand can be wed ed within the hook-shaped portions; This ormation can In ap lying the cable-support to the strand one of tlie arms C, Fig. 2, or the hook-shaped portion D, Fig. -3 is hooked upon the strand; and the support being-brought toward the 'strandwill enter and be en aged by the hookshaped portion B. Then y a twistin motion on the ring A the other arm C 'or o'okshaped portion D can be sprung by and,

snapped upon the strand and will clutch the same with a grip which will prevent any longitudinal movement of the support when the cable is being drawntherethrough.

Having thnsfully described my invention,

what I claim as new and useful is- In combination with a supporting strand or wire, an aerial-cable support consisting of side, said hook-shaped portion so positioned relative to one another as to exert tension u on' the strand from o posite sides and c utch the strand-wirewitli specified.

In testimony whereof I have hereunto af fixed my signature in the presence of two subscribing witnesses;

CHARLES L. BROWN.
